kouhei, fs: It looks like this benchmark has a long history of being bimodal. Is this a known issue?

Not sure it's the test as such. I suspect this bot isn't quite behaving though. (Notice how the big jumps occur in the ref-curve too.)

 Issue 616524  has been merged into this issue.

Kicked off a new bisect

The test has stabilized.
